About the species

The White-faced Ibis is a slender, medium-sized wading bird known for its long, down-curved bill and shimmering dark plumage. In Patagonia, it is often seen in flocks, probing shallow wetlands and flooded fields. Breeding adults are distinguished by a white border around the face and reddish legs and eyes. Outside the breeding season, their facial markings are less distinct, but their iridescent feathers remain a key feature. Social and vocal, these ibises are often found in groups, flying in loose formations or feeding together. Their presence is a sign of healthy wetland ecosystems, as they rely on these habitats for nesting and foraging.

Habitat

Prefers shallow freshwater marshes, lagoons, flooded meadows, and the edges of lakes and rivers across Patagonian lowlands.

Foraging

Feeds by probing mud and shallow water for insects, crustaceans, and other invertebrates, often in groups.
